I had been successfuly using the scanner of my EPSON Stylus DX4250 on Ubuntu (32bit) since I've bought it years ago.
Now I've updated to 11.10 64bit and it is not working anymore.
Have heard of some issues regarding USB, and some others regarding HAL, but I'm not sure where to start looking.
Here is what
[53778.567908] usb 2-1.2.4: new high speed USB device number 10 using ehci_hcd [53779.874059] usb 2-1.2.4: usbfs: process 25525 (usb) did not claim interface 0 before use
Doing a reboot, this is what I get:
[ 72.024538] usb 2-1.4: new high speed USB device number 6 using ehci_hcd [ 73.266142] show_signal_msg: 30 callbacks suppressed [ 73.266145] simple-scan: segfault at 9691a85 ip 00007f146f3131a4 sp 00007f145fffbe00 error 4 in libc-2.13.so[7f146f2ca000+195000] [ 73.322406] usb 2-1.4: usbfs: process 2027 (usb) did not claim interface 0 before use [ 146.794098] usb 2-1.4: USB disconnect, device number 6
